Description

[Detailed description of the invention]

[0001]

The present invention relates to a garbage storage for compressing and storing general waste from restaurants, cafeterias, supermarkets, condominiums, apartment houses, hotels, hospitals, department stores, schools, food processors, etc. The present invention relates to a tank, and more particularly, to a pusher type garbage storage tank.

[0002]

2. Description of the Related Art Conventionally, as this kind of garbage storage tank, there is, for example, one shown in FIGS. FIG. 6 shows a small rectangular box 39 having an opening / closing lid 38 on the upper surface.
There is a discharge drive in the hopper inside. This garbage storage tank has the advantages of being small and having a small floor space, and the input side has been devised in various ways, and is widely used in practice.

[0003] Fig. 7 shows a drum type dust storage tank having a structure in which dust put in from an inlet 41 at one end of a container 40 is sent to a discharge side 42 by a lead of a screw as the drum rotates. It is.

[0004]

However, the one shown in FIG. 6 cannot compress the dust and cannot sufficiently collect the dust to the upper part because the hopper for collecting the dust is turned over at the time of discharge. However, there is a problem that a large wasteful space portion is formed. Further, since the discharge drive section of the hopper is in the dust, repair, inspection, repair, and the like cannot be performed if the dust is contained, and there are many drawbacks.

In the case shown in FIG. 7, when dust is thrown in, the outlet is normally closed, so that the dust sent by the lead has no place to go at the end and escapes to the center, and is sent from one to the next. And come back from the center. Only after the whole is packed does full-scale compression take place. However, the objects in contact with the lead do not have a place to escape this time, so if the dust is in a bag, the bag may be cut into pieces, and in some cases, the cut vinyl may stick to the lead, causing an action such as sticking. It is easy to cause trouble. In addition, since full-scale compression is performed after almost the entire body is compressed, a considerable amount of horsepower is used for compression, and a small horsepower immediately stops due to overload. Furthermore, in the discharging process, the drum is rotated after opening the discharging side, and the discharging operation is performed by the reed, so that the first discharging can be performed well, but when the amount of the inside becomes small, the outer side (center) of the reed rather than pushing with the reed. Trash
There are various problems that 00% cannot be discharged.

Next, the operation of the above device will be described. First, to input garbage, open the input door (16) and open the input port (1).
Put garbage into the main body container (1) via 5). When the opening door (16) is opened, the limit switch turns off,
At the same time, the interlock function operates and each solenoid valve is demagnetized. Therefore, even if the switch of the operation panel 31 is operated by mistake, each cylinder does not start operating.
The safety of the input user when inputting garbage is ensured.

Next, after introduction of refuse, the turned the door (16) is closed limit switch is turned ON, the solenoid of the electromagnetic switching valve V ₃ and V ₄ is energized, first lower pusher (22) forward movement Is carried out, and the dust that has fallen in front of the push plate portion (a) of the lower push (22) is pushed forward. Next, when the lower pusher (22) retreats, the upper pusher (2)
4) moves forward and the terrace (c) of the lower pusher (22)
The debris on the garbage is dropped by the push plate portion (b) in front of the lower pusher (22). This series of operations is performed with the input door (1
Perform 6) each time it is closed. Every time this operation is performed, the stored dust is compressed. Lower pusher (2
Garbage in front of the 2) becomes full, been an increase in the head-side pressure of the lower pusher driving hydraulic cylinder (25), pressure switch P ₂ exceeds the predetermined pressure is activated, the electromagnetic switching valve V
₃ is returned to the neutral position and held at the origin position shown in FIG. Thereafter, each time the input door (16) is closed, only the upper pusher (24) operates to push the dust forward by the push plate portion (b) and compress it.

The main container (1) in the reservoir portion of the upper pusher driving hydraulic cylinder (26) the head-side pressure exceeds a predetermined pressure when the pressure switch P ₁ is actuated operation panel 31 is filled with rubbish Turn on the emission warning lamp to notify the garbage manager that garbage must be discharged. The garbage is discharged according to the following procedure. When the input door (16) is open, the discharge operation is interlocked as described above, so that the input door (16) must be closed. Next, the packer truck, which is a collection truck, is stopped at a predetermined position. The up / down switch is turned on and the up / down drive hydraulic cylinder (5) is driven to raise the front portion of the main body container (1) to a predetermined level, and the outlet of the storage section (9) to the level of the garbage inlet of the packer truck. When the discharge conveyor (14) is attached, the discharge conveyor (14) is lifted until the discharge conveyor (14) is substantially horizontal. When the level matches, the open switch of the discharge door (10) is turned ON to open the discharge door (10). Next, when the discharge switch is turned on, the lower pusher (22) moves forward, and accordingly, the upper pusher (24) advances to move the lower pusher (2).
After the trash in front of 2) is dropped from the discharge port (9) onto the discharge conveyor (14), the upper pusher (24) is retracted by a predetermined distance, and only the upper pusher (24) moves forward to move the upper pusher. The dust in front of (24) is dropped in front of the lower pusher (22), and the lower pusher (22) advances again to drop the dust on the discharge conveyor (14).
The trash on the conveyor (14) is transported and discharged to a packer truck. When the garbage has been discharged, the packer truck runs away. Thus, the discharge switch is turned off and the discharge door (1
0) is closed, the down switch of the up / down switch of the main body container (1) is pressed, and the main body container (1) is returned to the original position, and the operation is completed. Each time the draining operation is completed, the front waste tank (6)
Also, remove the rear waste tank (7) and clean the inside,
Install in the original position.

The upper pusher (24) and the lower pusher (2)
As the sequence operation 2), various sequences other than the above embodiment can be considered. For example, after throwing in dust, the upper pusher (24) performs reciprocating operation to perform storage and compression, and the lower pusher (22) is used only for discharging,
Normal compression can also be performed by the upper pusher (24).

According to the above-described apparatus, the upper and lower pushers (24, 22) are provided. By repeatedly operating the pushers (22) back and forth, waste such as dust is reliably compressed, and the space of the storage tank is reduced. Efficiency is improved. In addition, it is compressed to the original shape due to the linear compression by the pusher, it is compressed neatly, it does not shatter the plastic bag etc. like a rotary type, and there is no space in the tank,
In addition, after discharge, there is a considerable amount that remains in the rotary type, whereas discharge can be performed 100% completely.
The driving noise can be significantly reduced as compared with the rotary type.

Furthermore, by varying the set pressure of the pressure regulating valve V _5, it is possible to change the compressive force of the upper and lower pusher driving hydraulic cylinders (25, 26) depending on the type of waste. It is easier to clean, maintain, and inspect than other types, and the body container (1) is inclined downward toward the discharge side and does not rotate in a box shape, so that it is easy to accumulate sewage and the subsequent processing is easy. It has many effects such as being able to discharge arbitrarily even if it is not full.

It is needless to say that the size of the garbage storage tank described in the present embodiment is an example, and the size can be variously changed.

[0025]

[Effects of the Invention] As described above, according to the present invention, it is possible to reliably compress waste such as garbage by always moving the upper and lower pushers forward and backward after the loading, and to push the upper and lower pushers every time the loading door is closed. If the compression is performed in the step (1), the storage amount of dust can be increased. In addition, since the compression and the feeding of the dust are performed by the linear motion of the pusher, the dust can be compressed neatly, and the dust can be completely discharged when the dust is discharged.
